timer elapsed

The recent work involves processing specific actions after a certain period of time. For example, when pressing a button, you need to restart the system after pressing at least 4s, and then use a timer to ensure accurate timing. The following implementation can be universal. Struct timer_list OS _timer_t; // defines the timer # define OS _timer_func (_ FN) \ void _ FN (unsigned long timer_arg) # define OS _

Elapsed event is raised in the application. You can then provide general processing by handling this event. For example, suppose you have a critical server that must remain operational 24 hours a day, 7 days a week. You can create a service that uses a Timer to periodically check the server and ensure that the system is turned on and running. If the system does not respond, the service can attempt to resta

In the JS mechanism, we all know that the general code is written in an event, only when the event is triggered, the code will be executed, such as$ (selector). Click (function () {alert (' Hello ')});As the above code, only when the trigger click event, will pop up "hello" greeting;However, when the timer is used, both in the event and in the event, it is executed at the time of loading, such asvar timer =

First, the concept of scheduling task function in Java is the main use of the Timer object, which in the internal use of multi-threaded way to handle, so it and multithreading technology is very large association. In the JDK, the timer class is primarily responsible for the ability to schedule tasks, that is, to start a task at a specified time, but the class that encapsulates the task is the TimerTask cl

The timer is used in the project. As the service is started as a timed task, the relevant operation is timed to the specified time, but I want it to be executed only once during the specified time, to avoid the problem of re-entry.First of all, a brief introduction to the timer, which is referred to as the timer refers to the System.Timers.timer, as the name impl
